Smoking has a range of negative effects on the respiratory system. It leads to poor lung function and increased risk of developing respiratory diseases such as chronic bronchitis and emphysema. It can also lead to irritation of the airways, inflammation, and damage to the alveoli (tiny air sacs in the lungs). Cigarette smoking is also a leading cause of cancer of the lung and other organs.
